It is always better to use multiple wallets, but I will not suggest among the wallet sites, I'll suggest to choose from hot wallet or cold wallet . Cold wallet are used by even those wallet sites and even exchange platforms, this keeps the currency safe, hot wallets have to be cared with more security, yet if people do not wish, they can surely choose those wallet providers and they will keep their coins till the private key etc are with the investor, there KYC will keep another layer of security.
